I have a 2003 Clio 16v Dynamique. The other night I got told about that something was flashing on it. I went out for a look. The bottom of the brake lights and the white light at the top of the bumper were flashing on and off. I tried opening the car with the button on the key, wouldn't open. Opened the car with the key in the door. Tried starting it and nothing. Thought it was the battery so got someone to jump start it. The lights and everything else are working fine, the button on the key opens and closes the car again. Tried starting it and the engine will not kick in. The red immobiliser light on the dash is flashing constantly. I had someone out to look at it but they couldn't get it to start. Any suggestions please????
